T. de Mello Física, Astronomía y Matemáticas Ultra Dark matter high energy cosmic rays Pierre Auger experiment We analyze the cosmic ray arrival direction map that would be observed if the source of ultra high energycosmic rays were the decay of dark matter particles in the halos of our galaxy and of the Andromeda galaxy(M31). To model the dark matter distribution throughout the halos we use two different density profiles, theMoore et al. and the Navarro-Frenk-White profile. The results show what would be seen by the Pierre Augerexperiment, since we take into account its exposure. We evaluate the dipole and quadrupole terms for theresulting maps in the two density profiles cases and compare them with the terms expected for an isotropic sky. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437116 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.37 |
